<span>The steps of speciation are identified as reproductive isolation and
genetic change. These can happen simultaneously or one after the other. This means
that the main aim is to have new species through evolutionary changes brought
by geographic barriers separating a population or due to behavioral change in a
sub-population and even being reproductively isolated. </span>
Answer: A. Increase in temperature
Coastal upwelling is the process in which the deep water rises above the top most water level as the wind pushes water offshore. Nutrients which are present in the bottom layer get available to organisms living in the uppermost layer. The deeper water lacks oxygen because the decomposition of organic matter at the bottom of the water body consumes up available oxygen. Also, because of these water layer turnover will result in thermocline: temperature variation among the layers of water. Bottom layer water because of such decomposition processes will have more temperature when this water rises in the upper layer due to upwelling this will increase the temperature of the upper layer.
